WARNING
Important Two-Component Material Information
312776F 9
Important Two-Component Material Information
Isocyanate Conditions
Material Self-ignition
Keep Components A and B
Separate
Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two component
coatings. ISO will react with moisture (such as humidity)
to form small, hard, abrasive crystals, which become
suspended in the fluid. Eventually a film will form on the
surface and the ISO will begin to gel, increasing in vis-
cosity. If used, this partially cured ISO will reduce perfor-
mance and the life of all wetted parts.
NOTE: The amount of film formation and rate of crystal-
lization varies depending on the blend of ISO, the
humidity, and the temperature.
To prevent exposing ISO to moisture:
• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere. Never
store ISO in an open container.
• Use moisture-proof hoses specifically designed for
ISO, such as those supplied with your system.
• Never use reclaimed solvents, which may contain
moisture. Always keep solvent containers closed
when not in use.
• Never use solvent on one side if it has been con-
taminated from the other side.
• Always lubricate threaded parts with ISO pump oil
or grease when reassembling.
Changing Materials
• When changing materials, flush the equipment mul-
tiple times to ensure it is thoroughly clean.
• Always clean the fluid inlet strainers after flushing.
• Check with your material manufacturer for chemical
compatibility.
• Most materials use ISO on the A side, but some use
ISO on the B side.
Spraying or dispensing materials containing isocya-
nates creates potentially harmful mists, vapors, and
atomized particulates.
Read material manufacturer’s warnings and mate-
rial MSDS to know specific hazards and precautions
related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufficient ventila-
tion in the work area. If sufficient ventilation is not
available, a supplied-air respirator is required for
everyone in the work area.
To prevent contact with isocyanates, appropriate
personal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.
Cross-contamination can result in cured material in
fluid lines which could cause serious injury or dam-
age equipment. To prevent cross-contamination of
the equipment’s wetted parts, never interchange
component A (isocyanate) and component B (resin)
parts.

the old color and loads a new color.
Solvent Push
The Solvent Push feature enables the user to save
some mixed material by pushing it out to the gun with
solvent. The feature requires an accessory solvent
meter. See page 63 for complete information.
Mix Fill Push
The Mix Fill Push feature enables the user to prevent
potlife expiration of material by mixing and flowing new
material through the Gun Flush Box. See page 64 for
complete information.
General Operating Cycle,
Sequential Dosing
1. The spray gun operator enters and loads the
desired recipe. The color change LED blinks while
recipe is loading, then turns solid when complete.
2. The operator presses the Mix key to begin
operation.
3. The ProMix 2KS controller sends signals to activate
the solenoid valves. The solenoid valves activate
Dose Valves A and B. Fluid flow begins when the
gun is triggered.
4. Components A and B are introduced into the fluid
integrator (FI) one at a time as follows.
a. Dose Valve A (DVA) opens, and fluid flows into
the integrator.
b. Flow Meter A (MA) monitors the fluid volume
dispensed and sends electrical pulses to the
ProMix 2KS controller. The controller monitors
these pulses and signals.
c. When the target volume dispenses, Dose Valve
A closes.
NOTE: The dispense volume of component A and B
is based on the mix ratio and dose size set by the
user and calculated by the ProMix 2KS controller.
d. Dose Valve B (DVB) opens, and fluid flows into
the integrator and is aligned proportionately with
component A.
e. Flow Meter B (MB) monitors the fluid volume
dispensed and sends electrical pulses to the
ProMix 2KS controller.
f. When the target volume is dispensed, Dose
Valve B closes.
System Operation
312776F 47
5. The components are pre-mixed in the integrator,
then uniformly blended in the static mixer (SM).
NOTE: To control output from the static mixer to the
gun, install an optional fluid pressure regulator.
6. Components A and B are alternately fed into the
integrator as long as the gun is triggered.
7. If the gun is not triggered for two minutes, the sys-
tem switches to Idle mode, which closes off the mix
manifold dose valves.
8. When the gun is triggered again, the ProMix 2KS
continues the process where it left off.
NOTE: Operation can be stopped at any time by
pressing the Standby key or shutting off the
main power switch.

General Operating Cycle, Dynamic Dosing
Overview
Dynamic Dosing provides on-demand proportioning,
eliminating the need for an integrator and therefore min-
imizing undesired material contact. This feature is espe-
cially useful with shear-sensitive and waterborne
materials.
A restrictor injects component B into a continuous
stream of component A. The software controls the dura-
tion and frequency of each injection. See FIG. 52 for a
schematic diagram of the process.
Dynamic Dosing System Parameters
The following parameters affect dynamic dosing perfor-
mance:
• Component A Flow: Ensure that the supply pump is
sized to provide sufficient and uninterrupted flow.
Note that component A provides majority of system
flow at higher mix ratios.
• Component B Flow: Ensure that the supply pump is
sized to provide sufficient and uninterrupted flow.
• Component A Pressure: Ensure precise pressure
regulation. It is recommended that the component A
pressure be 5-15% lower than the component B
pressure.
• Component B Pressure: Ensure precise pressure
regulation. It is recommended that the component B
pressure be 5-15% higher than the component A
pressure.
NOTE: When using dynamic dosing it is very important
to maintain a constant, well-regulated fluid supply. To
obtain proper pressure control and minimize pump pul-
sation, install a fluid regulator on the A and B supply
lines upstream of the meters. In systems with color
change, install the regulator downstream of the
color/catalyst valve stack.

Select a Component B Restrictor Size
Install the 15U955 Injection Kit in the fluid manifold as
explained in the ProMix 2KS Installation manual. Use
the charts provided in that manual to select an appropri-
ate restrictor size based on the desired flow and mix
ratio.
Turn On Dynamic Dosing
1. On the EasyKey press the Setup key to access
the Set Up Home screen. Select “System Configu-
ration” to access the configuration screens. FIG. 53.
2. Navigate to System Configure Screen 4. Select
“DD” option from the “Dose Size” drop down menu.
FIG. 54.
3. Selecting “DD” in System Configure Screen 4
makes the DD Setup mode available. See FIG. 55.
To enable DD setup mode, select On in the DD
setup mode drop down menu. This disables Off
Ratio alarms E-3 and E-4, allowing uninterrupted
setup and tuning.
NOTE: Do not use the material mixed when in DD setup
mode, as it may not be on ratio due to the disabled
alarms.
NOTE: If DD setup mode is not turned Off at the end of
setup, it will automatically turn off 3 minutes after initia-
tion of a Mix command.

Balancing A/B Pressure
If component B pressure is too high, it will push the com-
ponent A stream aside during B injection. The valve will
not open long enough, causing a High Ratio alarm.
If component B pressure is too low, it will not be injected
in sufficient volume. The valve will stay open too long,
causing a Low Ratio alarm.
Selecting the correct component B restrictor size and
balancing the A/B pressures will keep the system in the
proper pressure range, resulting in a consistent mix
ratio.
FIG. 57 shows the A to B pressure balance, read at the
proportioner inlet. It is recommended that the compo-
nent B pressure be 5-15% higher than the component A
pressure to keep the system in the control range, hold
the proper mix ratio, and obtain properly mixed material.
If pressures are not balanced (“B Pressure Too High” or
“B Pressure Too Low”), it may not be possible to hold
the desired mix ratio. The system will generate an off
ratio alarm and stop operation.
NOTE: In multi-flow rate systems, it is recommended
that you set up the system to run properly at the highest
flow rate, to ensure adequate fluid supply across the
flow rate range.
In dynamic dosing, component A dose valve is con-
stantly on. Component B dose valve will cycle on and
off; one cycle every 0.5 – 1.0 seconds indicates proper
balance.
Monitor system performance by watching the EasyKey
display for warning messages which provide information
on system performance, and adjust pressures accord-
ingly. See Table 6 on page 51.

Air Flow Switch (AFS) Function
Air or Air-assisted Guns
The air flow switch (AFS) detects air flow to the gun and
signals the ProMix controller when the gun is triggered.
The AFS functions with the flow meters to ensure that
system components are functioning correctly.
For example, if a flow meter fails or clogs, pure resin or
catalyst could spray indefinitely if the ProMix does not
detect the condition and intervene, which is why the
AFS is so important.
If the ProMix detects through the AFS signal that the
gun is triggered, yet there is no fluid flow through the
meter, a Dose Time Alarm (E-7 or E-8) occurs after 40
seconds and the system shuts down.
Operating Without Air Flow Switch
It is not recommended to run without an air flow switch.
If a switch fails, replace it as soon as possible.
Airless Gun
It is not recommended to use an airless gun with the
ProMix 2KS. Two issues can arise from operating with-
out an air flow switch:
• Without a gun trigger/air flow switch input the Pro-
Mix 2KS does not know it is spraying and will not
generate a Dose Time Alarm (E-7 or E-8). This
means there is no way to detect a failed meter. You
could spray pure resin or catalyst for 2 minutes with-
out knowing.
• Since the ProMix 2KS does not know it is spraying
because there is no gun trigger/air flow switch input,
it will go into System Idle (E-15) every 2 minutes
when in Mix mode.
System Idle Warning (E-15)
This warning occurs if the ProMix is set to Mix ,
and 2 minutes have elapsed since the system received
a flow meter pulse.
In applications using the AFS, triggering the gun clears
the warning and you can start spraying again.
Without the AFS, triggering the gun does not clear the
alarm. To start spraying again, you must press Standby
, then Mix , then trigger the gun.

Start Up
1. Go through the Pre-Operation Checklist in Table 8.
2. Turn the AC Power Switch ON (I = ON, 0 = OFF).
Graco logo, software revision, and “Establishing
Communication” will display, followed by Status
screen. See page 20.
At power up the system defaults to Recipe 61,
which is not a valid recipe number. Initiate a
color change to Recipe 0 or a valid recipe num-
ber (1-60).
In bottom left corner, the system status dis-
plays, which can be Standby, Mix, Purge, or an
alarm notification
3. Make sure that the Booth Control is working. The
active recipe number should display and the
Standby LED should be lit.
4. If this is the first time starting up the system, purge it
as instructed in Purging Fluid Supply System,
page 60. The equipment was tested with lightweight
oil, which should be flushed out to avoid contaminat-
ing your material.
5. Make sure that the Booth Control is in Standby
mode.
Table 8: Pre-Operation Checklist
Checklist
System grounded
Verify all grounding connections were made. See
the Installation manual.
All connections tight and correct
Verify all electrical, fluid, air, and system connec-
tions are tight and installed according to the
Installation manual.
Check air purge valve tubing
Check the air purge valve supply tube daily for
any visible solvent accumulation. Notify your
supervisor if solvent is present.
Fluid supply containers filled
Check component A and B and solvent supply
containers.
Mix manifold valves set
Check that mix manifold valves are set correctly.
Start with the settings recommended in Mix Mani-
fold Valve Settings, page 51, then adjust as
needed.
Fluid supply valves open and pressure set
Component A and B fluid supply pressures should
be equal unless one component is more viscous
and requires a higher pressure setting.

6. Adjust component A and B fluid supplies
as needed for your application. Use low-
est pressure possible.
7. Do not exceed the maximum rated work-
ing pressure shown on the system identification
label or the lowest rated component in the system.
8. Open the fluid supply valves to the
system.
9. Adjust the air pressure. Most appli-
cations require about 80 psi (552
kPa, 5.5 bar) air pressure to operate properly. Do
not use less than 75 psi (517 kPa, 5.2 bar).
10. If using a gun flush box, place the gun into the box
and close the lid. Press the Purge key on the
Booth Control. The purge sequence automatically
starts.
If the gun flush box is not used, trig-
ger the gun into a grounded metal
pail until the purge sequence is com-
plete.
When done purging, the Booth Control automati-
cally switches to Standby mode.
11. Adjust the flow rate.
The fluid flow rate shown on the EasyKey Status
screen is for either component A or B, depending on
which dose valve is open. The fluid supply lines on
the screen highlight to show which dose valve is
open.
Watch the fluid flow rate displayed on the Status
screen while the gun is fully open. Verify that the
flow rate of components A and B are within 10% of
each other.
If the fluid flow rate is too low: increase air pres-
sure to component A and B fluid supplies or
increase the regulated fluid pressure.
If the fluid flow rate is too high: reduce the air
pressure, close the fluid manifold dose valves fur-
ther, or adjust the fluid pressure regulator.
NOTE: Pressure adjustments of each component will
vary with fluid viscosity. Start with the same fluid pres-
sure for component A and B, then adjust as needed.
NOTE: Do not use the first 4-5 oz. (120-150 cc) of mate-
rial as it may not be thoroughly mixed due to alarms
while priming the system.
12. Turn on atomizing air to the gun. Check the spray
pattern as instructed in your spray gun manual.
NOTE: Do not allow a fluid supply tank to run empty. It
is possible for air flow in the supply line to turn gear
meters in the same manner as fluid. This can lead to the
proportioning of fluid and air that meets the ratio and tol-
erance settings of the equipment. This can further result
in spraying uncatalyzed or poorly catalyzed material.

Purging
There are 4 purging procedures in this manual:
•Purging Mixed Material (below)
•Purging Using Recipe 0 (page 60)
•Purging Fluid Supply System (page 60)
•Purging Sampling Valves and Tubes (page 62)
Use the criteria listed in each procedure to determine
which procedure to use.
Purging Mixed Material
There are times when you only want to purge the fluid
manifold, such as:
• end of potlife
• breaks in spraying that exceed the potlife
• overnight shutdown
• before servicing the fluid manifold assembly, hose
or gun.
Solvent purges the component B (catalyst, right) side of
the mix manifold and the inner tube of the integrator. Air
purges the component A (resin, left) side and the outer
tube of the integrator.
1. Press the Standby key on the Booth Control.
2. Set the solvent supply pressure regulator at a pres-
sure high enough to completely purge the system in
a reasonable amount of time but low enough to
avoid splashing or an injection injury. Generally, a
setting of 100 psi (0.7 MPa, 7 bar) is sufficient.
3. If using a gun flush box, place the gun into the box
and close the lid. Press the Purge key on the
Booth Control. The purge sequence automatically
starts.
If the gun flush box is not used, trig-
ger the gun into a grounded metal
pail until the purge sequence is com-
plete.
When done purging, the Booth Control automati-
cally switches to Standby mode.
4. If the system is not completely clean, repeat step 3.
NOTE: If necessary, adjust purge sequence so only
one cycle is required.
5. If spray tip was removed, reinstall it.
6. Adjust the solvent supply regulator back to its nor-
mal operating pressure.
Read Warnings, page 7. Follow the Grounding
instructions in your system Installation manual.
To avoid splashing fluid in the eyes, wear eye protec-
tion.
Trigger the gun to relieve pressure.
If you are using a high pressure gun, engage the trig-
ger lock. Remove spray tip and clean tip separately.
If using an electrostatic gun shut off the electrostatics
before flushing the gun.
Trigger the gun to relieve pressure. Engage trigger
lock.

Purging Using Recipe 0
Recipe 0 is typically used:
• in multiple color systems to purge out material lines
without loading a new color
• at the end of a shift to prevent hardening of cata-
lyzed material.
To setup Recipe 0, go to Advanced Setup. Select the
Recipe tab and change the Recipe to 0. The Recipe 0
Setup Screen appears. Set the chop times from 0-999
seconds in increments of 1 second.
1. Press the Standby key on the Booth Control.
2. If using a gun flush box, place the gun into the box
and close the lid.
3. Select Recipe 0 and press Enter .
4. If a gun flush box is not used, trigger
the gun into a grounded metal pail
until the purge sequence is com-
plete.
5. The color change LED blinks while Recipe 0 runs
and turns solid after purge sequence is complete.
6. If the system is not completely clean, you can
repeat Recipe 0 by pressing Enter .
Purging Fluid Supply System
Follow this procedure before:
• the first time material is loaded into equipment*
• servicing
• shutting down equipment for an extended period of
time
• putting equipment into storage
*Some steps are not necessary for initial flushing,
as no material has been loaded into the system
yet.
1. Press the Standby key on the Booth Control.
2. Attach solvent supply lines as follows:
•Single color/single catalyst systems: discon-
nect the component A and B fluid supplies at
the flow meter inlets, and connect regulated sol-
vent supply lines.
•Multiple color/single catalyst systems: dis-
connect only the component B fluid supply at
the flow meter inlet and connect a regulated sol-
vent supply line.
•Multiple color/multiple catalyst systems:
connect the solvent supply lines to the desig-
nated solvent valve on the color and catalyst
valve stacks. Do not connect a solvent supply to
either flow meter.
Trigger the gun to relieve pressure.
If you are using a high pressure gun, engage the trig-
ger lock. Remove spray tip and clean tip separately.
If using an electrostatic gun shut off the electrostatics
before flushing the gun.

312776F 63
Solvent Push Feature
The Solvent Push feature enables the user to save
some mixed material by pushing it out to the gun with
solvent. The quantity saved is 50% of the potlife volume
entered in Advanced Setup Screen 1 on page 35. If
there are 2 guns, the smaller potlife volume is used.
Solvent Push requires an accessory solvent meter (MS).
Order Graco Part No. 16D329 S3000 Solvent Meter Kit.
See manual 308778.
1. See FIG. 69. Install the solvent meter (MS) on the
side of the fluid station, as explained in the ProMix
2KS Installation Manual.
2. To enable Solvent Push, select “Solvent” or “3rd
Valve,” as desired. See Option Screen 2, page 33.
NOTE: If you are using a 3rd purge valve instead of the
solvent purge valve to run the Solvent Push feature,
connect the solvent supply line from the solvent meter to
the inlet of the 3rd purge valve.
NOTE: The system must be in Mix to initiate Solvent
Push.
3. Press and hold the Mix key for 5 seconds
to turn on Solvent Push. The green Mix LED will
light and the Recipe LED will blink. The system will
close the Dose Valves (DVA, DVB) and open the
Solvent Purge Valve (SPV).
4. The system will dispense solvent to push the mixed
material out to the gun. The Booth Control display
alternately shows dashes and the percent remaining
(0-99%) of the 50% of the potlife volume.
NOTE: To manually interrupt Solvent Push, press the
Standby key. The Solvent Purge Valve (SPV) or
3rd purge valve will close. To re-enter Solvent Push,
press the Mix key.
5. When the total solvent dispensed exceeds 50% of
the potlife volume, the system will go into Standby
mode.
6. Perform a manual purge or recipe change to purge
the remaining mixed material. This will clear the sys-
tem out of Solvent Push, allowing you to resume
Mix mode.
NOTE: Once the system senses that solvent exceeds
50% of potlife volume, attempts to re-enter Solvent
Push will cause an Overdose A/B Alarm (E-5, E-6).

Mix Fill Push Feature
The Mix Fill Push feature enables the user to prevent
potlife expiration of material by mixing and flowing new
material through the Gun Flush Box.
Mix Fill Push requires an accessory Gun Flush Box for
each gun that will use this feature. Order Graco Part No.
15V826 Fun Flush Box Kit. See manual 312784.
NOTE: If the gun is not in the box the Mix Fill Push fea-
ture will not operate.
NOTE: The Mix Fill Push operation will run every time
the Potlife alarm occurs with the gun in the box. Unat-
tended systems can therefore repeatedly perform this
operation as the potlife keeps happening.
Mix Fill Push requires a Gun Flush Box for the gun. If
two guns are used, each requires a Fun Flush Box for
this feature to operate. The second Gun Flush Box must
be configured as a Special Output. See Configure
Screen 5 on page 31.
To enable Mix Fill Push, select “Mix Fill Push” in the
Auto Dump field. See Option Screen 2, page 33.
1. The system gets a Potlife alarm.
2. The buzzer will do a double "chirp" every 4 seconds
to indicate an impending Mix Fill Push.
3. After waiting for the 2-minute Auto Dump time the
system will run the Mix Fill Push.
NOTE: On a one-gun system the gun must be in the
GFB. On a 2-gun system both guns must be in the
GFBs.
4. If one of the guns in not in the GFB, the system will
not perform any of the Mix Fill Push or Auto Dump
operations. The system will retry every 30 seconds
in case the gun is then installed in the GFB.
5. With the guns in the GFBs, the system will propor-
tion mixed material through the guns in order to
reset the potlife volume.
6. The alarm is cleared.
7. The event is logged in the Alarm Log as two alarms:
E-5 Overdose A and E-6 Overdose B.

Meter Calibration
312776F 65
Meter Calibration
Calibrate the meter:
• The first time the system is operated.
• Whenever new materials are used in the system,
especially if the materials have viscosities that differ
significantly.
• At least once per month as part of regular mainte-
nance.
• Whenever a flow meter is serviced or replaced.
NOTE:
• K-factors on the Calibration Screen are
updated automatically after the calibration pro-
cedure is completed.
• K-factor values on the screen are viewable only.
If needed, you can manually edit the K-factors
in Advanced Setup Screen 4 (page 36) or
Recipe Setup Screen 5 (page 41).
• All values on this screen are in cc, independent
of the units set in Configure Screen 1.
• The controller will use the active recipe
K-factors for meter calibration. The active
recipe must be recipe 1 to recipe 60. Recipes
0 and 61 do not have K-factor values.
1. Before calibrating meter A or B, prime the system
with material. For a color/catalyst change system,
make sure the color/catalyst valve is open.
2. Shut off all spray or dispense devices connected to
the ProMix.
3. Close both fluid shutoff valves and sampling valves.
4. Place the beakers (minimum size - 250 cc) in hold-
ers. Put the sampling tubes into the beakers.
NOTE: If tubes need replacing, use 5/32 in. or 4 mm
OD tubing.
5. On the EasyKey, press the Setup key to access
setup screens.
6. Select Recipe & Advanced Setup and press the
Enter key to select.
To avoid splashing fluid in the eyes, wear eye protec-
tion. The fluid shutoff valves and ratio check valves are
retained by mechanical stops that prevent accidental
removal of the valve stem while the manifold is pres-
surized. If you cannot turn the valve stems manually,
relieve the system pressure, then disassemble and
clean the valve to remove the resistance.
7. Press the Right Arrow key to select the Calibra-
tion Screen. Press the Enter key to select
either A Meter, B Meter, or Solvent. Press the Down
Arrow key and select Start from the menu. Start
only one at a time.

a. To avoid splashing, slowly open sampling
valves.
b. For more accurate calibration, adjust the valve
to dispense at a flow rate similar to your produc-
tion spray flow rate.
c. Dispense a minimum of 250 cc; make sure
enough material is dispensed to accurately read
the volume with your beaker. The A and B vol-
umes do not have to be equal or at any particu-
lar ratio.
d. Close sampling valve tightly.
9. The volume that the ProMix measured displays on

NOTE: For maximum accuracy, use a gravimetric
(mass) method to determine the actual volumes dis-
pensed.
11. If the screen and actual volumes are different, enter
the actual dispensed volume in cc for A, B, or Sol-
vent Volume field, and press the Enter key.
If the value was substantially different, repeat the
calibration process.
NOTE: If the screen and actual volume is the same
or if for any reason you want to cancel the calibra-
tion procedure, scroll to Abort on the Calibration
Screen menu and press the Enter key.
12. After the volume for A, B, or Solvent is entered, the
ProMix 2KS controller calculates the new flow meter
K-factor and shows it on the Calibration Screen.
NOTE: K-factor values on the screen are viewable
only. If needed, you can manually edit the K-factors
in Advanced Setup Screen 4 (page 36) or Recipe
Setup Screen 5 (page 41).
13. Always purge sampling valves after calibrating
meters. Use one of the following methods.
•Follow the Purging Sampling Valves and
Tubes procedure, page 62.
• Place the sampling valve fluid tubes into a com-
patible cleaning fluid (TSL or solvent) or cap
them.
NOTE: If fluid hardens in sampling tubes, replace
them with 5/32 in. or 4 mm OD tubing.
14. Make sure both sampling valves are closed and
both fluid shutoff valves are fully open.
15. Before you begin production, clear the system of
solvent and prime it with material.
a. Go to Mix mode.
b. Trigger the gun into a grounded metal pail until
mixed material flows from the gun nozzle.

Color Change Procedures
Multiple Color Systems
1. Shut off air to the gun.
2. Place the gun in the gun flush box if used, and close
the lid.
3. Switch to Standby mode at the Booth Control.
4. Use the scroll keys, or , to select the new
color. Press Enter to begin the color change
sequence.
5. If a gun flush box is not used, trigger
the gun into a grounded metal pail
until the color change sequence is
complete.
6. When the color change indicator light stops flashing
on the Booth Control, the color change sequence is
complete.
NOTE: The color change timer does not start until
the gun is triggered and fluid flow is detected. If no
flow is detected within 2 minutes, the color change
operation aborts. The Booth Control enters Standby
mode at the previous color.
7. When you are ready to spray, remove the gun from
the gun flush box if used, and close its door.
NOTE: The gun flush box door must be closed for
the atomizing air valve to open.
8. Press the Mix key to start spraying.
Single Color Systems
1. Follow procedure for Purging Fluid Supply Sys-
tem, page 60.
2. Load the new color. See Start Up, page 53.
3. Press the Mix key to start spraying.
Color Change Sequences
FIG. 71 through FIG. 80 illustrate various color change
sequences. See Table 9 to determine which figure to
reference, based on the recipe change and system con-
figuration. The time sequences are detailed in the fol-
lowing paragraphs.
NOTE: For software version 2.04.xxx and older, the sys-
tem uses the color/catalyst purge and fill times from the
new recipe.
NOTE: See Setup Mode on page 25 to select purge
sources and set desired purge, chop, and fill times.
NOTES:
• The system uses old recipe data for the purge cycle.
However, it opens the new color/catalyst valve
based on the new recipe data.
• The system uses the new recipe data for the fill
cycle.
• For the one gun flush box (GFB) option, the spray
gun must be inserted in the GFB during the entire
color change cycle (purge and fill). The GFB trigger
output will be on during the recipe change cycle.
• For the two gun flush box (GFB) option, both spray
guns must be inserted in the GFBs during the entire
color change cycle (purge and fill). The system will
turn each GFB trigger output on and off based on
the preset time for each gun.
• For Special Outputs options, the system will turn
each output on and off based on the preset times.
Each Special Output has two different start times
and durations.
• For systems without dump valves, the First Purge
begins after the Color/Catalyst Change steps are
completed.
• Dump Valve B is required for a Catalyst Change
system.
• When going from Recipe X to Recipe 0, only the
purge cycle data from Recipe 0 is used.
• When going from Recipe 0 to Recipe Y, only the fill
cycle data from Recipe Y is used.
Color Change

Color Purge/Dump
• This sequence flushes out the color with solvent,
from the color valve to the Dump A valve.
• The color change solvent valve and the Dump A
valve open during the Purge Time.
• The color change solvent valve closes when the
Purge Time expires.
Color Fill
• This sequence fills the line with the new color all the
way to the Dump A valve.
• The new color valve and the Dump A valve open
during the Fill Time.
• The new color valve and the Dump A valve close
when the Fill Time expires.
Catalyst Purge/Dump
• This sequence flushes out the catalyst with solvent,
from the catalyst valve to the Dump B valve.
• The catalyst change solvent valve and the Dump B
valve open during the Purge Time.
• The catalyst change solvent valve closes when the
Purge Time expires.
Catalyst Fill
• This sequence fills the line with the new catalyst all
the way to the Dump B valve.
• The new catalyst valve and the Dump B valve open
during the Fill Time.
• The new catalyst valve and the Dump B valve close
when the Fill Time expires.
First Purge
Select the First Purge Source (air, solvent, or 3rd valve)
and First Purge Time. For most applications, air is
selected.
The system purges the old material from the dose
valves to the gun, using only the selected purge media
(usually air). The selected purge valve opens during the
First Purge Time and closes when the time expires.
Chop Cycle
Select the Chop Type (air/solvent or air/3rd valve) and
Chop Times.
The air purge valve opens only during the air chop
cycle, and the solvent (or 3rd valve) opens only during
the solvent chop cycle. The number of chop cycles is
determined by dividing the Total Chop Time by the sum
of the Air and Solvent Chop Times.
Final Purge
Select the Final Purge Source (air, solvent, or 3rd valve)
and Final Purge Time. For most applications, solvent is
selected.
The system fills the line with solvent from the dose
valves to the gun, using only the selected purge media
(usually solvent). The selected purge valve opens
during the Final Purge Time and closes when the time
expires.
Fill
This sequence fills the line from the dose valves to the
gun, and is also referred to as the mixed material fill.
The system begins mixing components A and B until the
Fill Time expires.

Alarms and Warnings
NOTE: Do not use the fluid in the line that was dis-
pensed off ratio as it may not cure properly.
System Alarms
System alarms alert you of a problem and help prevent
off-ratio spraying. If an alarm occurs, operation stops
and the following occurs:
• A red LED illuminates steadily or blinks on the
Booth Control.
• Booth Control displays an alarm E-Code, E-1 to
E-28. See FIG. 81.
• Buzzer sounds (for E-2 only; see page 29 to set for
all alarms).
• Status bar on the EasyKey Display shows the alarm
E-Code with a description (see Table 10).
System Warnings
Table 10 lists the System Warning Codes. Warnings do
not stop operation or sound an alarm. They are saved in
the date/time stamped log, which can be viewed on a
PC, using the ProMix 2KS Web Interface (see manual
313386).
To Reset Alarm and Restart
NOTE: When an alarm occurs be sure to determine the
E-Code before resetting it. See Table 10. If you forget
which E-Code occurred, use the Alarms Screens (page
24) to view the last 10 alarms, with date and time
stamps.
To reset alarms, see Table 11. Many alarms can be
cleared by simply pressing the Alarm Reset key.

E-1: COMM ERROR
Cause Solution
No power to the EasyKey. Connect power to EasyKey.
No power to Fluid Station. The intrinsically safe power
cable between the EasyKey and Fluid Station is not con-
nected.
Verify that the cable is correctly connected. See Installa-
tion manual.
No power to Fluid Station. The fluid control board fuse is
blown.
Verify condition of fuse and replace if necessary. See
Repair-Parts manual.
The fiber optic cable between the EasyKey and Fluid
Station is not connected.
Verify that the cable is correctly connected. See Installa-
tion manual.
The fiber optic cable is cut or bent. Verify that the cable has not been cut or bent at a radius
smaller than 1.6 in. (40 mm).
Dirty fiber optic cable ends. Disconnect fiber optic cable ends and clean with a
lint-free cloth.
A communication cable or connector failed. Replace cable.
E-2: POTLIFE ALARM
Cause Solution
The potlife time has been exceeded for the mixed mate-
rial. Press the Alarm Reset key to stop the audible
alarm. Purge the system with solvent, fresh mixed mate-
rial, or a new color:
•Solvent Purge - See Purging Mixed Material on
page 59. The system purges until the preset purge
time is complete.
•New Mixed Material Purge - Go to Mix mode and
spray the required volume to restart the timer.
•Color Change - Perform a color change, page 67.
NOTICE
To prevent mixed material from curing in the equip-
ment, do not shut off power. Follow one of the solu-
tions at right.
Alarm Troubleshooting
82 312776F
E-3: RATIO HIGH ALARM
Sequential Dosing System
The mix ratio is higher than the set tolerance on the previous dose cycle.
Dynamic Dosing System
The mix ratio is higher than the set tolerance for an A to B component volume comparison.
Cause Solution
There is too little restriction in the system. • Check that the system is fully loaded with material.
• Check that the supply pump’s cycle rate is set prop-
erly.
• Check that the spray tip/nozzle is properly sized for
the flow and application, and that it is not worn.
• Check that the fluid regulator is set properly.
If the alarm occurs during start up, after purging, the flow
rate was probably too high.
Restrict gun needle travel to slow down the initial fluid
delivery rate until fluid hoses are loaded with material.
If the alarm occurred after you were spraying for some
time, the pressures from the fluid supplies could be
unbalanced.
Adjust component A and B fluid supply regulator pres-
sures until they are about equal. If the pressures are
already about equal, verify that component A and B dose
valves are operating properly.
Slow actuation of the component A or B valves. This can
be caused by:
Manually operate the Dispense A and B solenoid valves
as instructed in the ProMix 2KS Repair-Parts manual to
check operation.
• Air pressure to the valve actuators is too low. • Increase air pressure. Air pressure must be 75-120
psi (0.52-0.84 MPa, 5.2-8.4 bar); 120 psi is recom-
mended.
• Something is restricting the solenoid or tubing and
interrupting valve actuation air.
• There may be dirt or moisture in the air supply. Filter
appropriately.
• A dose valve is turned in too far. • Refer to Table 7: Mix Manifold Valve Settings,
page 53, for adjustment guidelines.
• Fluid pressure is high and air pressure is low. • Adjust air and fluid pressure. See recommended air
pressure above.

E-4: RATIO LOW ALARM
Sequential Dosing System
The mix ratio is lower than the set tolerance on the previous dose cycle.
Dynamic Dosing System
The mix ratio is lower than the set tolerance for an A to B component volume comparison.
Cause Solution
There is too much restriction in the system. • Check that the system is fully loaded with material.
• Check that the supply pump’s cycle rate is set prop-
erly.
• Check that the spray tip/nozzle is properly sized for
the flow and application, and that it is not clogged.
• Check that the fluid regulator is set properly.
If the alarm occurs during start up, after purging, the flow
rate was probably too high.
Restrict gun needle travel to slow down the initial fluid
delivery rate until fluid hoses are loaded with material.
If the alarm occurred after you were spraying for some
time, the pressures from the fluid supplies could be
unbalanced.
Adjust component A and B fluid supply regulator pres-
sures until they are about equal. If the pressures are
already about equal, verify that component A and B dose
valves are operating properly.
Slow actuation of the component A or B valves. This can
be caused by:
Manually operate the Dispense A and B solenoid valves
as instructed in the ProMix 2KS Repair-Parts manual to
check operation.
• Air pressure to the valve actuators is too low. • Increase air pressure. Air pressure must be 75-120

E-5: OVERDOSE A/B DOSE TOO SHORT ALARM and
E-6: OVERDOSE B/A DOSE TOO SHORT ALARM
E-5: the A dose overshoots and, when combined with B, is too large for the mix chamber capacity.
E-6: the B dose overshoots and forces an A side dose that, when combined with B, is too large for the mix chamber
capacity.
Cause Solution
Valve seal or needle/seat are leaking. Check FIG. 11
Totals Screen on page 23. If A and B are dosing simul-
taneously (sequential dosing only), there is a leak.
Repair the valve (see valve manual 312782).
Sampling valve is leaking. Tighten or replace valve.
Flow meter fluctuations caused by pressure pulsations. Check for pressure pulsations:
1. Close all the manifold valves.
2. Turn on the circulating pumps and all the booth
equipment (such as fans and conveyors).
3. Check if the ProMix 2KS is reading any fluid flow.
4. If the ProMix 2KS shows there is fluid flow and there
are no leaks from the gun or any other seals or fit-
tings, the flow meters are probably being affected by
pressure pulsations.
5. Close the fluid shutoff valve between the fluid supply
system and the flow meter. The flow indication
should stop.
6. If necessary, install pressure regulators or a surge
tank on the fluid inlets to the ProMix 2KS to reduce
the fluid supply pressure. Contact your Graco distrib-
utor for information.
Slow actuation of component A or B valves. See E-3: RATIO HIGH ALARM and E-4: RATIO LOW
ALARM, pages 82-83.
Running a high mix ratio and a high flow rate. It may be necessary to restrict the flow rate through the
component B dose valve by adjusting its hex nut (E).

E-7: DOSE TIME A ALARM and E-8: DOSE TIME B ALARM
E-7: gun trigger input is active (AFS or Integration) and fewer than 31 A meter pulses were detected during the
dose time selected.
E-8: gun trigger input is active (AFS or Integration) and fewer than 31 B meter pulses were detected during the
dose time selected.
Cause Solution
System is in Mix mode and gun is only partially
triggered, allowing air but no fluid to pass through gun.
Fully trigger the gun.
Fluid flow rate is too low. Increase flow rate.
Dose time setting is too short for the current flow rate. Increase the dose time setting.
Flow meter or cable failed or flow meter clogged. To check meter sensor operation, remove meter cap to
expose sensor. Pass a ferrous metal tool in front of the
sensor.
If there is a meter or cable failure, you will see a large dif-
ference between the amount of fluid dispensed and the
flow meter volume displayed by the EasyKey. Clean or
repair meter as necessary. Also see meter manual
308778.
Follow Meter Calibration procedure, page 65.
Slow actuation of component A or B valves. See E-3: RATIO HIGH ALARM and E-4: RATIO LOW
ALARM, pages 82-83.
The supply pump is not turned on. Turn on the supply pump.
There is an air leak downstream from the air flow switch. Check the air lines for leaks and repair.
The air flow switch is stuck open. Clean or replace air flow switch.
System is in Mix mode with 0 volume entered for Min
Material Fill Volume (see Option Screen 1, page 32),
and Fuse F1 is blown.

Cause Solution
Automation has requested that the system abort all oper-
ations.
Abort operations. Troubleshoot automation system.
E-11: PURGE VOLUME ALARM
Cause Solution
ProMix 2KS solvent flow switch is not activated while
purging.
Verify that the gun is not shut off and that the solvent
flow switch is activated while purge is taking place.
Minimum flush volume is not achieved. Increase solvent supply or decrease minimum volume
setting.
No meter pulses during Color/Catalyst Dump. Color change solvent supply not set up or functional.
Check Color Change setup.
Table 11. Alarm Troubleshooting
Alarm Troubleshooting
312776F 87
E-12: CAN COMM ERROR ALARM
Cause Solution
Communication between the Color Change Module and
the Fluid Station is interrupted.
• Verify that all cables are connected securely and that
the Color Change and Booth Control power LEDs
turn on. If the power LED does not turn on, the prob-
lem is probably caused by a bad connection. The nut
on the connector must make at least 5 complete
turns to ensure a good connection. If the power LED
still does not light, the cable or board is bad.
• Check the color change board DIP switch settings.
See the Installation manual.
• Check the fluid plate board DIP switch setting. An
incorrect setting will not cause E-12 alarms, but a
correct setting will help prevent E-12 caused by elec-
trical noise. See the Installation manual.
• Check EasyKey software version (displayed at
power up for all versions and when the lock key is
pressed for version 2.02.000 and above). If older
than 1.06.002, upgrade. Be sure to save settings
through BWI or AWI before upgrading, as they will
be erased.
• The sticker on the color change board shows the
software part number and version, for example
15T270 1.01. If the version is older than 1.01,
replace the board.
• If all software versions and DIP switch settings are
correct and you still have E-12 alarms, then the sys-
tem has a bad connection, bad cable, or bad circuit
board. Use a multimeter on the CAN connectors to
test whether there is a good connection between
systems. If there is, you have a bad circuit board. If
there is not, you have a bad connector, connection,
or cable.
• Appears on the EasyKey display if the unit is pro-
grammed for Manual Mode, and a booth control is
not connected.
• The dip switch settings on the Color Change Module
were changed (see manual 312787) while the power
was on. Cycle the power to clear the alarm.
• The dip switch configuration on the Color Change
Control Module (see manual 312787) is setup incor-
rectly.
Communication between the Color Change Module and
the Fluid Station is interrupted. The fluid control board
fuse is blown.
Verify condition of fuse and replace if necessary. See
Repair-Parts manual.
Communication between the Booth Control and the Fluid
Station is interrupted.
Verify that the cable is correctly connected.

E-13: HIGH FLOW ALARM or E-14: LOW FLOW ALARM (may also be set as Warnings)
Cause Solution
Fluid system is producing too much or too little flow. Troubleshoot fluid system for restrictions, leaks,
exhausted fluid supply, incorrect settings, etc. Increase
or decrease flow rate, as required.
E-15: SYSTEM IDLE WARNING
Cause Solution
Mix input is high, but the gun has not been triggered for 2
minutes.

312776F 89
E-19: I/O ALARM
Cause Solution
The Mix and Purge digital inputs are on at the same time. Ensure that only one input is on at a time. At least 1 sec
delay is required when switching from Mix to Purge or
vice versa.
NOTE: The I/O alarm incorporates several sub-alarms relating to internal data issues, as detailed below. These
alarms are only seen in the Alarm log or through BWI or AWI, and may not apply to all software versions.
Fluid Plate Reboot (FP Reboot): Occurs if the system
detects a fluid plate control board reboot or power cycle
not triggered from the EasyKey. The system reverts to
Recipe 61, and mixed material may be in the lines.
Flush the system or perform a color change. If possible,
identify the origin of the reboot or power cycle.
Autokey Lost: Occurs if the Autokey is lost or changed
after having been detected. (A short term loss of the
Autokey will not be registered.) Some system functions
may become unavailable. For example, an automatic
system will not respond to PLC or robot control.
Reinstall the Autokey, or verify that the Autokey is set
properly.
Illegal Source: Occurs if a recipe outside of the range
1-60 is detected as the source data for global recipe data
copies. This is possible if an invalid configuration file is
sent to the EasyKey.
Verify that the source data is from a valid recipe (1-60).
2K/3K Error: Occurs if the recipe data is incompatible
with the current Autokey setting (2K or 3K). This is possi-
ble if the Autokey is changed or an invalid configuration
file is sent to the EasyKey.
Verify that the Autokey is set properly or that the configu-
ration file is valid.
Init Error: Occurs if the recipe data codes specifying the
type of machine they were made on are not what is
expected. For example, a 3KS machine receives a con-
figuration file originally made on a 2KS machine.
Verify that the configuration file is valid.
Config Error: Occurs if a configuration file sent to the
EasyKey specifies a different hardware setup than what
exists. For example, the configuration file specifies 2
color change boards but only 1 is present.
Verify that the configuration file specifications and the
hardware conform.
Range Error: Occurs if a valve used in a recipe is not
present in the current hardware setup. For example, a
recipe calls for valve 30 but the system has only 12
valves.
Verify that the recipe specifications and the hardware
conform.
Level Control (LC) Error: Occurs if level control data is
received by the EasyKey, and the current Autokey set-
ting (2K or 3K) has changed since the level control data
was originally initialized.
Verify that the Autokey is set properly.
Level Control (LC) Range Error: Occurs if level control
data includes a valve range exceeding the capability of
the machine.
Set level control data correctly.
Modbus (MB) Overflow: Occurs if the Modbus connec-
tion to a PLC experiences data overflow.
Verify the Modbus protocol to the EasyKey.

90 312776F
E-20: PURGE INITIATE ALARM
Cause Solution
System detects atomizing air to the gun when purge is
selected.
Shut off gun air.
For systems with a gun flush box, gun is not in the box
when purge is selected.
Place gun in gun flush box. Verify that gun flush box is
operating properly.
For systems with auto dump on, gun is not in the box
when auto dump is initiated.
Place gun in gun flush box. Verify that gun flush box is
operating properly.
For systems with a gun flush box, Fuse F2 is blown. Verify condition of fuse and replace if necessary. See
Repair-Parts manual.
E-21: MATERIAL FILL ALARM
Cause Solution
For systems with minimum mixed material fill volume
entered, the system detects that fill volume is not
achieved during mixed material fill time.
Check for restrictions or leaks in the fluid supply system.
Check if the fill volume is properly configured:
• Adjust fill volume.
• Adjust fill time.
For systems without color change and with minimum
mixed material fill volume entered, Fuse F1 is blown.
Verify condition of fuse and replace if necessary. See
Repair-Parts manual.
E-22: TANK A LOW ALARM, E-23: TANK B LOW ALARM, or E-24: TANK S LOW ALARM
Cause Solution
The tank volume reaches the low-level threshold. The EasyKey screen will display the alarm and prompt
the user to do one of the following:
• Refill tank volume to clear the alarm.
• Resume mixing by selecting “Spray 25% of remain-
ing volume.” If this selection is chosen, a second
alarm will occur after 25% of the remaining volume is
mixed. Refill tank volume to clear the alarm.
Table 11. Alarm Troubleshooting
Alarm Troubleshooting
312776F 91
E-25: AUTO DUMP COMPLETE ALARM
Cause Solution
A potlife alarm is active for more than 2 minutes, the gun
flush box is enabled and gun is in the gun flush box, and
an auto dump flush sequence is complete.
Be sure to spray all mixed material before potlife expires.
E-26: COLOR/CATALYST PURGE ALARM
Cause Solution
System detects no meter pulses, or a disruption in meter
pulses lasting longer than 1 second throughout the
Color/Catalyst purge time duration.
Check that meter cable is connected.
Clean or repair meter.
E-27: COLOR/CATALYST FILL ALARM
Cause Solution
System detects no meter pulses, or system must detect
at least 10cc of material from each side throughout the
Color/Catalyst fill time duration.
Check that meter cable is connected.
Clean or repair meter.
Gun, dump valve, or correct color/catalyst valve not
open.
Open the valve.
Exhausted fluid supply. Check fluid level and refill if necessary.
Switch settings (S3-S6) on color change board do not
match hardware configuration.
Verify that color change board switches are set correctly.
See installation manual.
Fuse F1, F2, or both are blown. Verify condition of fuses and replace if necessary. See
Repair-Parts manual.
E-28: MIX FILL PUSH COMPLETE
